A few points here. 1. If the car was not running it most likely was not hydro locked, if it was running it might have no damage to terminal damage so the engine would need to be replaced.
Did you open the spark plugs and inspect the cylinders? 2. There could be damage to electrical parts that will have to be replaced.
3. You have a very complex vehicle which makes this process more difficult to repair. 4.
MB is the most expensive non-exotic car make to repair. I am guessing the first thing is to have it hooked up to MB computer and see if you get any info and maybe an error list to start working through.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
